We all love an Easter egg, whether its references to Game of Thrones in Altered Carbon to Deadpool namechecking DC in his second outing.
Fans have come to expect nods to anything and everything in outing on both the big and small screens.
However, it seems that many of us – except those die-hard Batman buffs – have all been missing one HUGE Easter egg from one of the BIGGEST comic book films of all time, Christopher Nolans The Dark Knight.
Starring Christian Bale as Batman and Heath Ledger in an iconic and career-defining role as The Joker, the film has gone down in the annals of movie history.
But what have we all been missing? The Jokers introduction to us is actually an Easter egg from the original Batman TV shot starring Cesar Romero as the Clown Prince of Crime.
The link is sad and strangely haunting white and blue clown mask that Ledgers Joker puts on for the bank robbery at the very beginning of the Dark Knight.
It exactly mirrors the mask that Romeros Joker uses in the 1966 episode The Joker Is Wild (season one, episode five) from Batman the TV series.
Reddit user Christianhbk shared a handy frame-by-frame picture of the Jokers wearing their masks on the site, much to the delight of many.
What can we say? Christopher and Jonathan Nolan delved deep into the mythology of the Dark Knight for all three of their films.
Were also sure this isnt the last obscure Easter egg that will surface from the now 10-year-old action film.
